The present invention relates to linecasting and composing machines and more particularly to signal controlled mechanism employed for the automatic operation and supervision thereof.

In the attainment of automatic control 'of present commercial types of linecasting and composing machines it -has been observed that the speedof operation whichis attainable by the signal sensing and mechanical selecting mechanism exceeds that at which the linecasting machine is capable of responding. Accordingly, devices have been perfected which serve tol introduce a time lag or delayfactor into the operation of the' automatic control mechanism so that there may result a reconciliation in certain instances where the speeds of the two devices are at 'varia somewhat longer period to complete` its function cycle than that period which isrequired by an operating unit to complete its-initiatlng cycle. In the case of duplicate release operations of similar characters, it has been found that a sumcient overlap exists in the release stroke of the second signal to extendfinto the', timeV interval occupied by the second release operation, so that in the case of twoduplicate character release operations the response of the linecasting or prinl. existing automatic control devices. VWheredmwcipal machine may be-adequateiy regulated by ever, a given signal is repeated more than once.

it has been observed that the occurrence of thev third initiating stroke isso far vin advance of the third consecutive operatingvcycle of the principal machine that itsassoiated matrix release device is incapable of arriving at its normal position in4 I Vsuilicien't time to respond thereto.

Accordingly an/object `of the present invention 'is the provision ,of apparatus responsive to characters repeated consecutively for introducing a delay factor in the operation of the control unit and therebyreconciling the inherent speed thereof with that of its associated linecasting machine. For the achievement of the foregoing purpose there is contemplated in accordance with the present invention, a record reader mechanisminvcluding a set of tape'sensing 'feeler levers and having associated with it a selectable -device conl ditioned by consecutive ones of a series ci similar charactersignalsA and eiective to arrest momentarily the continued operation of the record si chinas. (ci. 19a-is) reader mechanism. As a result of such selection, there is permitted the intervention of a time delay factor which not only blocks the selection and actuation of the particular selectable element cycle of operation ofthe record reader mechafollowing hereinafter in" which similar reference characters are used to indicate. correspondingparts throughout, and in which A Fig. l is a diagrammatic perspective view of a record reader mechanism having embodied therein principles representative of the present invention,

Fig. 2 is a longitudinal sectional view through a mechanism similar to that illustrated in Fig. 1, v

and

Fig. 3 is a timing chart featuring the periods and duration of certain functionsinconnection with the present invention in terms of their principal operating elements.` This chart includes a number oi'curves, the tops of which represent operated or effective conditions asproduced by the cams on shaft 22, andthe bottoms of which represent the opposite conditions.

In its preferred embodiment, the present invention has been adapted to an automatic control mechanism resembling in general appearance the one shown in U. S. Patentl No. 2,091,286. A record reader mechanism is indicated by the reference character Il. which consists brieny of a set ot feelerlevers or tape sensers I2, each providedV with a feeler,pin i3 and pivoted on a common shaft-I4." 'The perforated tape or control form is previously prepared in a perforating machine where it receives permutatively variant transverse; rows oi holes. Each row relates to a line composition character or to a collateral composition function, where the tape is, employed in the. control of linecasting machines, and may be said to comprise ,the area, transversely, inwhich a basic number of pertorations may occur permutably. .Because the presence or absence of a perforation is controlled by perforating mechanism ing the sensing and transfer mechanism of the record reader mechanism in its alternative positions corresponding terminology will be employed hereinafter.

Individual springs I5, Fig. l, tend normally to maintain the feeler levers I2 in their vextreme counterclockwise position and in this they are cyclically opposed by the action of a reciprocating bail I5 which is comprised of a transversely extending rod I1 traversing beneath the horizontal extensions I8 integrally formed with the feeler levers I2. 'I'he curve I2 on Fig. 3 indicates the normal cycle of operation of the feeler levers I2. The reciprocating bail I6 is pivotally supported at an intermediate point thereof and includes a depending portion which carries a follower roller I9 spring urged against the periphery of a feeler lever operating cam 2I. The latter 4is carried upon a shaft 22 which is driven through a clutch from a suitable source of power. In addition to cam 2I, shaft 22 also carries a tape feed cam 23 and cam 24 which serves to reciprocate periodically a set of transfer levers to be described later.

During its cycle of rotation, tape feed cam 23 imparts reciprccatory movement to a follower roller 25 carried by a second class lever arm 26 pivoted at 21 and adapted to communicate its movement to a tape feed arm 28. At the opposite extremity of arm 28 there is pivotally carried in upright positiona tape feed pawl 29. 'I'he reciprocatory movement of pawl 29 which engages the teeth of a ratchet wheel 3I imparts step-by-step motion to a tape feed shaft 32 which carries a sprocket feed wheel 33 whose pins coincide with the central row of perforations conventionally provided in control forms of the class employed in connection with permutation signal operating mechanisms. A spring 34 urges lever arm 28 in a clockwise direction about pivot 21 until its horizontally extending ledge 35 impinges upon an adjustment screw 36 which extends through the reciprocating lever 26 giving to the tape feed pawl 29 an operative cycle as represented by the curve 29 in Fig. 3. It will be noted, however, that the movement of the tape feed pawl 29 upwardly does not cause the movement of the tape but that this is done by spring 34 during the receding part of tance of one step by the pawl 29, following which bail I6 is returned, permitting the individual springs I5 to urge their associated levers I2 in a counterclockwise direction. The presence or absence of a hole in the tape determines finally the distance of angular movement of any of the levers I2, depending upon whether the feeler pins I3 pass through the tape as where a perforation is encountered or whether they are blockedby the tape as where an imperforated position is found. The setting of the combined set of levers I2 is thereafter communicated by an associatedset of transfer levers 31, Fig. 1, to a set of intermediate connector bars 38. This operation occurs at a time indicated by the hump in the curve 31 of Fig. 3, and may be seen to complete its full rockingmotion during the time that the feeler levers I2 are sensing the tape. This operation is motivated by cam 24 upon whose peripheral surface there rides a follower roller 39 carried by one arm of a bell crank 4I whose other arm supports a transversely extending shaft 42 upon which the several transfer levers 31 and special transfer lever 4S 'are rotatably supported. Counterclockwise movement of bell crank 4I thrusts the transfer levers 31' upwardly, causing their i`head projections 43 to encounter ones or the others of the feeler lever shoulders 44. In accordance with the positions of the several levers I2, the transfer levers 31 are rocked clockwise or coun terclockwise, causing their disc extensions 45, Fig. 2, to move the connector bars 38 and 5I correspondingly. The connector bars 38 thereby receive a setting which corresponds to the perforations in the tape during each given cycle of operation and they in turn communicate this setting to a set of notched code selector bars 45.

Intermediate the tape sensing levers I2 there is pivotally supported on shaft I a transfer setting lever 41 resembling somewhat the general class -of levers I2, but differing therefrom in that it is not provided with a sidewardly extending arm which carries a feeler pin I3, nor is the lever 41 provided with a horizontally extending projection I8 served by the reciprocating power bail I6, but in lieu of a projection I8, this lever carries a downwardly and leftwardly extending arm 48. As may be understood from the absence of a feelerpin I3, lever 41 is not positioned under the control of the presence or absence of a perforation in the control form but instead is posi 'tioned by a selectably initiated device which is responsive to repeated character siognals,

Cooperating with the transfer setting lever 41 is a transfer lever 49 similar to transfer levers 3T and a connector bar 5I resembling connector bars 38. Instead of bar 5I being articulated to a code lselector bar 46, however, it is provided instead -with a so-called blocking bar 52 whose projections 53 are distributed so as to clear each of the individually selectable pull bars 54 under normal conditions when any one of them is otherwise receivable within the code notches appearing in the general class of code'bars 46, and to block the selective movement thereof during an idle cycle of rotation as will be more fully explained hereinafter.

In contradistinction to the general class of pull bars 54 there may be noted in Fig. l a pair of certain function performing pull bars 540, the purpose of which is explained in the above referred to Patent No. 2,090,654. The lug attributes of blocking bar 52 are designed to normally ,prevent or block the selective clearance of pull bars 540 while the projections 53 clear the general class of pull bars 54, as indicated in Fig. 2. Subsequently when blocking bar 52 is shifted, however, either in accordance with the repeat selection bail or in accordance with a rail shift delay operation, a reversal of conditions is effected with the projections 53 blocking the general class of pull bars 54 but affording a selecting clearance (in the event of 'a rail shift signal) to the rail shift pull a transversely extending bail shaft 56 carried by a repeat signalv selecting bail 51. The latter member is pivoted about shaft 58 and comprises several integrally formed extremities including a blocking arm 59 which Vextends unwardly and rightwardly, as viewed in Fig. 2, a blocking arm ll which extends downwardly and rightwardly,

' of repeated character signals results in a diiferand leftwardly. In addition-to these arms, a vertically extending arm termed a latch arm als'o is integrally formed with lever 5 1 and is adapted'to be engaged by a shoulder I4 presented by the foremost extension of a horizontal arm l! of a latch bail t0.- Bail is urged in a clockwise direction by a spring 61, Fig. 2, and is limited in i its movement by the engagement of a follower roller Il carried thereby which rides the periphery\ of latch release cam I9 secured to and therefore rotatable with the record reader operating shaft 22. e

In addition to its control of bail il. latch re- Y lease cam 69 also governs the operation of a bell crank assembly'comprised of a lever 1l, a lever arm 12, )and a'spring 13 which tends to hold the assembly yieldably together. and the angle between lever 1I and lever arm 12 constant. The

cooperation between members 1I and 1211s determined by the abutting relation of a projection 14 carried bylever arm`12 and a blocking arm 1l carried by lever 1 I `Illg. 2. It will be seen that cam` 69, during its rotation in a clockwise direction first releases' the repeat selecting bail latch 66, as indicated by the hump in curve Fig. 3, and thereafter upon encountering the follower roller 10 of lever 1l causes the counterclockwise rotation `of the bell Acrank assembly comprising lever 1i and arm 12, as indicated by the hump in curve ll-ll'. Curves BI- and 8I-69 have been illustrated as separate curves, though they represent the mechanical result of the same actuating element; namely, cam 69 performing upon two independent mechanisms. The extremity of arm 12 is presented beneath the downwardly and leftwardly extending arm 48 of transfer setting lever 41, causing the latterv under the original actuation of cam.` to be shifted clockwise against the tendency of its individual spring I not shown. This movement on the part of transfer setting lever 41 from its Aso-called marking position to its spacing position under the cyclic stimulation of latch release cam 89 merely constitutes anidle operation ordinarily because of the fact that before its associated T- shaped transfer lever 4! can communicate the' change of position to its articulated bars 5I and 52. the apex' of cam 69 moves on permitting the bell crank assembly 'il-12 and transfer setting lever 41 to resume normalcy. The contingency entresponse on the part. of members 41, 2|, an 1|-12 as will be understood later.

As stated before, the cam projections `5I in either oftheir rest positions may be found on one side or the other of thetransversely extending rod ltbut in passing from lone position to the other they engage rod il, causing the latter to be cammed upwardly to rotate the repeat selecting bail 51 against the tendency of its spring 10. This movement of ball 51 is permitted during each cycle when latch I8 is vreleased'by cam I9, freeing the upstanding projection which is .normally withheld by shoulder $4. Thus, while the initiation of a cycle of operation, as evidenced by the rotation of shaft .22, causes rgpeat bail $1 to be freed and to rotate counterclockwise under the stimulus of spring` 16, rod 56 dropping between the projections 55, it will be understood that subseduently in the' cycle when the T-levers j 21 are shifted in accordance. with 'a change of signal that the movement of connectors 3l and 5l camming rod 5I upwardly, through the agency v spacing signal.

of' cam projections 55, serves in this way to restore bail-l1 to its latched position` Only in the event of repeated signals in which case connectors Il and Il remain dormantvls bail 51 permitted to continue in its counterclockwise position beyond the period of a single cycle of operation;

j As a resulto! its movement, the upwardly and :is provided on one of its arms with a stop lug 82,

its other arm' `83 being connected through spring t4 with the blocking arm 6I of bail lll In this way, spring 84 tends to hold lever 8i in the .posi- `tion indicated in Fig. 2 with respect to the bail 51. Upon the counterclockwise rotation ofthe "latter, however, a lug 8B carried by lever 8l comes into engagement with the blocking arm 15 of the lever 1I, which forms part of the aforementioned bell crank assembly for shifting the transfer setting lever". In sov doing, the spring 84 becomes distended vslightly until an instant subsequently in the cycle of rotation of shaft 22 when the apex of cam 89 encounters the follower roller 10 of lever 1|. This event causes lever 1| to be rotated counterclockwise until its blocking arm is withdrawn from the path of lug 88. Thereafter spring 2.4 being under tension causes lever Il to continue. in a counterclockwise direction until lug 85 falls behind arm 1l. 'I'his causes lever 1i to remain in its counterclockwis'e or operated position. after the apex of cam 68 has passed, imparting through spring 13 and lever arm 12 a clockwise torque to lever 41, and shifting the latter from its normal position which coincides with a marking signal to its opposite position When upon the subsequent rotation ofcam shaft 22, 'cam 24 carried thereby causes the operationV of transfer bell crank 4I, the par- I ticular T-shaped transfer lever 4l associated' with-the transfer setting lever 41 will then shift connector 5i rlghtwardly. causing its projection 55 to cam out rod I6 and rock bail i1, in this way restoring the latter to its latched condition.

behind the shoulder i4 of latch I8. As a4 i'ur-v ther result of the movement of connector bar 5|. blocking bar l2, which is normally at rest in its marking position, is now shifted rightwardly, presenting its projections into the Apath o'f the.. several push bars I4 and momentarily preventing. the particular Voney of them which happens to be otherwise in a selected condition from consummating its operation and performance.l 4 The camming-of rod 5I results in a clockwise rotation of repeat selecting bail 51 and the withdrawal of blocking projection 11 from behind vthe lug 18 of tape feedv arm 2B.' Conse- 'quently there is permitted the reciprocatory movement o i' tape feed arm 28 under the actua- 'tion of cam 23 and spring 34 moving the tape step-by-step in its normal procedure until another plurality of similar character signals is encountered. Meanwhile the continued rotation of shaft 22 again rocks the T-shaped transfer levers 31 causing their lugs to collide with those of thetape feeler levers I2 and the setting lever 41 but the only change of signal noted at this coinciding with a time will be the reshift to marking position of lever 41. Accordingly, connector bar 5| restores, withdrawing blocking bar 52 from its effective position. y

To prevent the selection of the repeat selecting bail 51 in response to certain repeated character signals, selectable blocking elements are provided which have been indicated 86 and 81. These memberslnclude transversely extending bail rods 88 and 89 each of which is presented opposite a transverse alignment of notches 9| corresponding in distribution to the particular signal for which repeated character delay is to be thus blocked out.

Among the signals for which repeatedv character delay is to be blocked out, bails 86 and 81 contemplate particularly the so-called blank and "rubout signals. Upon the selection of either of these levers, its bail rod 88 or 89 is received within its associated transverse alignment of notches 9|. When this occurs, its upstanding portion is presented in front of one of the projections 92 of arni 82 so that if the same signal be repeated, the failure of movement of any of the connectors 38 or 5I does not result in the selection of bail 51 by reason of the intervention of lever 86 or 81. Thus, while bail 51 is made responsive to repeated character signals generally, the means 86 and 81 illustrate one mode of exceptingcertain signals from the class to be served by the selection of repeat bail 51.

The reference character 93 illustrates a duplex rail delay selecting lever indicated 16 in Patent 2,090,654 referred to above. This element is selectively conditioned to interpose a time delay interval during the movement of the shiftable duplex rail and means are provided to prevent the selection of the repeat selecting bail 51 as a result of the continued operation of shaft 22 during the time in which the duplex rail is being actuated. 'For this purpose a downwardly and leftwardly extending .projection 94 is integrally formed with lever 93 to be presented opposite a sidewardly extending lug formed with arm 6| of lever 51. When duplexrail selecting lever 93 is selectively actuated, itV pivots about point k95 until projection 94 is brought into alignment with the lug of arm 6|.v During the succeeding cycle of rotation of shaft 22 because the connectors 38 and 5| remain dormant, the lever 51 might otherwise seek its selected or operated position due to a failure of the cam projections 55 in ejecting the transverse shaft 56, but because arm 5| is blocked by portion 94, this selection is prevented.

Operation 3|. It remains in'this position until nearly 260V` of rotation, whereupon it descends, actuating the tape feed sprocket shaft 32.' Curve I2 represents the movement of the tape sensing levers |2. At the `beginning of a cycle these levers are permit- 'Y ted to enter a row of perforations in thetape, as

shown *by the rise of the curve. Thelevers rest in this position for a short time. This is repre- .the final 100 of rotation.

sented by the plateau portion of the curve and in this position levers I 2 continue until shortly after 200 of revolution, at which time they are withdrawn. The instant of withdrawal of levers l2 may be noted as preceding by a small margin the instant at which pawl 2 9 actuates shaft 32 to advance the tape one step distance.

Curve 51-69 represents the movement of latch pawl 65 in its release of the repeat-selection element 51. This release operation is consummated within the first of rotation, following which latch pawl 65 is not again actuated during a given cycle. Curve 31 represents the movement of transfer levers 31, which operation is performed by cam 24 acting on bell crank lever 4|. Comparing curve 31 with curve l2, it will be noted that the transfer operation is completely consummated within the span during which the sensing levers |2 are in their upper or tape sensing position. Finally, curve 8|, 69, 1|, etc., represents the instant at which cam 69 engages and moves the bell crank assembly, including arms 1| and 12. This operation is consummated within In the event that auxiliary arm 8| is pressing against projection 15, as is the case during a repeat signal selection, the actuation of lever 1| by cam 69 permits auxiliary arm 8| to pass projection 15, which thereupon will move behind extremity 15, holding lever 1| in its actuated position, and through its spring articulation 13 with arm 12, will cause transfer setting lever 41 to be moved to its spacing position and be found there upon the subsequent actuation of transfer levers 31 and 49. Accordingly, curves 8|, 69. 1|, etc., represents the instant of actuation of lever 1|. y To illustrate how the present device functions in connection with repeated character selection where the characters exceedxtwo in number, it will be supposed that a series'A of three repeated characters is received in consecutive order on a perforated tape. Accordingly there will be contemplated four cycles of operation, the first two coinciding with the first two similar signals the third cycle coinciding with an idle rotation for the purpose of interposing a single cycle of revolution to obtain a delay, and a fourth cycle for dennting the incidents of operation during which the mechanism performs a delayedoperation and is restored to normal performance.

Under ordinary conditions of operation, the repeat selecting bail 51 may be found in its unoperated position latched behind shoulder E4 of latch member 66 as iilustrated in Fig. 2. At the initiation of thefirst cycle of rotation which may be observed in terms of rotation of shaft 22, cam 23 acting on follower roller 25, rotates lever 26 counterclockwise, sending the pawl feed arm 28,upwardly in opposition to its return spring 34. At about the same time, cam 69 encounters roller 68, unlatching member 66 and freeing bail 51 which thereupon drops into selected position, Viz., with rod 56 between the projections 55 and lug 11 behind lug 18. Also at this time, due to the rotation of cam 2|, the several feeler levers I2 are permitted to respond to their springs I5 and to sense the particular condition in the tape then in line with their feeler pins 3. Following shortly thereafterhe apex of cam 24 actuates the transfer bell crank assembly 4|, causing the transfer levers 31 to be thrust against the feeler levers |2 and transfer setting lever 41. This movement of the transfer levers 31 is of short duration, and the bell crank 4| is promptly returnedrdue to the short apex of cam 24.

movement of connectors 38 and 5I has resulted in the camming out of rod 56 and in the rotation of bail 51 in a clockwise direction. Because at this time the latch 68 is found in its normal position, upstanding arm 63 or bail 51 is again latched behind shoulder The tape feed cam 23 then withdraws its apex, permitting tape feed arm 28 'to actuate pawl 29 and to advance the tape a distance of one step.

Meanwhile a signal having been communicated to the, selector bars 46 there was permitted the selective conditioning of a particular pull bar El. At the same time the apex oi cam 69 encountered lever 1i, which forms part of the bell crank assembly with lever arm, 1t, and in so doing, the two were actuated momentarily in contemplation of a repeat character signal. Because the particular signal diiers from a preceding one, however, nothing resulted from this nioveinent.1

The mechanism has at this time completed one cycle of rotation and is about to enter upon a succeeding cycle where, in accordance with the supposition, a second character similar to therst occurs in the tape. The second cycle of rotation isl similar to `the cycle 'just described upto the point where transfer levers 31 are urged against the feeler. levers I2 and transfer setting lever Il,

. In this case, because the signal is similar to the preceding signal there results no movement of the connector bar 38 or' 5l when thetransfer levers 3l vare actuated, consequently bail Il,

when released by a latch 65 andcam .69, Ais pernon. ThisX msubstaneeis the situation or the' mltted'to remain in its counterclockwise position presenting its projection 11:' behind the 1und1# oiz' integral arm 19 'associated with the tape reed arm 2B. This prevents the return movement of arm 28 at a time when cam 23 in the preceding cycle withdrew iniavor `of return spring 3l.

As a further resulto! the inert condition of repeat selecting bail 51, companion lever 8| is 'permitted to travel to its counterclockwise position until lug li abuts the projection 15 pending lthe subsequent operation ot cam t9, when lever 1i' and 'projection 1l are withdrawn. Towards the conclusion of the second cycle, when the apex of cam I0 actuates lever 1I, the assembly inj cluding arm 12 causes transfer setting lever l1 to be shifted to its space vcondition as aforedescribed, and this shift operation, which ordinarily exists for but a slight interval and is restored immediately, ln the instant case continues Vbecause-lug l5, under influence of spring, is v nolw presented behind blocking arm 1l, latching the latter member in its so-called operated posiseveral elements at the conclusion of the second enters upon its third cycle of rotation. The release of latch 88 by cam 69 atthe start vcycle of rotation o! shaft 22 and when the ,latter because tape feed arm 28 has been blocked in its z return movement and continues to remainv in its4 opstanding-position without having advanoeame tape. t'lhe actuation of thev feeler levers 'I2 at Vu this time Vi's'alao of no consequence becausethe Avqualify certain of the third cycle is ineiectual because selectingl ings of saidelementsffor'V preceding signal continues inthe tape sensing position. The first eiiective operationv in this cycle results when bail 24 actuates the transfer levers 31, causing a shifting of the connecting rod il which has meanwhile received a different signal from the preceding vone due to the movementv of transfer setting lever 41 by the bell crank assembly V1I-12. As a result of the movement of connector barV Il, rod 56 pf repeat selecting bail 5l is again cammed out, causing the upblocked and their selection accordingly prevented.

This intervention onvthe part of blocking bar B2 prevents another selective operation among the pull bars 54 which would otherwise result because the code bars are still positioned in accordance with the second signal. l

The relatching of bail 51 causes its projection 11 to be withdrawn and the movement of tape .feed arm 28 reinstated, so that at the conclusion of the third cycle, the tape is advanced t0 align the .third consecutive signal opposite the pins i3 of the feeler levers l2. The return movement of bail 51 carrying with it companion lever 8l, also releases the bell crank assembly 1i-12, permitting transfer setting lever 41 to resume its normalposition. Thus atthe conclusion oi the third cycle the several elements are restored in contemplation of the third signal and the fourth v cycle of rotation. The sensing oi the third consecutive signal and the consequent operation oi the several elements corresponds identically with fications and variations may be instituted without departing from the spirit or scope thereof.
